First Aid Measures: Description of necessary first aid measures: In case of poisoning by any exposure route contact the National Poisons and Hazardous Chemicals Information Centre, PO Box 913, Dunedin. Phone , 0800 POISON. Workplace facilities: Hygiene Practices: No specific facilities required. Standard emergency equipment must be available. Avoid contact with skin and eyes and inhalation of concentration or spray mist. When mixing or applying, wear protective clothing, including face shield, impervious gloves and footwear. If clothing becomes contaminated with product, remove clothing immediately. DO NOT eat, drink or smoke while using. Wash hands and exposed skin thoroughly with soap and water before meals and after work. Wash protective clothing daily after work. Eye: Skin: Inhaled: Ingestion: Treatment: If product gets in eyes wash it out immediately with water for at least 15 minutes. If skin contact occurs remove contaminated clothing and wash affected areas thoroughly with soap and water. Move person to fresh air and keep at rest until recovered. Apply artificial respiration if necessary. Wash out mouth with water. Give water to drink. Do not give anything by mouth to an unconscious person. Keep patient at rest and seek medical advice. For local contamination treatment should be symptomatic after decontamination. For systemic poisoning initial treatment should be symptomatic and supportive. 5. Fire-Fighting Measures. Decomposition: Extinguishing media: Recommended Protective clothing: In case of fire, hydrogen chloride, oxides of nitrogen and oxides of carbon may be formed. Water spray, carbon dioxide, dry powder, foam. Use media suitable to cause of fire. When fighting a major fire wear an air-supplied respirator. Wear protective equipment. Page 2 of 7

Personal Precautions: Environmental Precautions: Procedure for spill: Emergency Procedures: Ensure suitable personal protection during removal of spillages. This means wearing eye protection, chemically resistant gloves, boots and overalls. Washings must be prevented from entering surface water drains or waterways. Keep all bystanders away. Wear goggles, half face-piece respirator with combined dust and vapour cartridge, full length clothing and PVC gloves. Contaminated material must be disposed of in accordance with all local authority requirements. For quantities up to 50kg of product bury in a secure approved landfill site. For quantities greater than 50kg seek advice from the manufacturer (use emergency contact number) before attempting disposal. Contain in a secure location until disposal method is established. Decontaminate the spill area with detergent and water and rinse with the smallest volume of water practicable. Procedure for Disposal: a)triple rinsing or preferably pressure rinsing containers with water. Add the rinsings to the spray tank. DO NOT dispose of undiluted chemicals on site. b) Burning of empty containers if circumstances, especially wind direction, permit is an alternative method. Do not burn unless in a suitable incinerator. c) Product or unused spray mix should be disposed of according to label instructions. 7. Handling and Storage. Handling Practices: Conditions for Safe Storage and Store Sire Requirements: Packaging: Flammability: Avoid contact with skin and eyes and inhalation of concentrate or spray mist. When using, do not eat, drink or smoke. Wash face and hands before eating, drinking or smoking. Store in a cool, dry, well ventilated place and protect from sunlight. Store in original container, tightly closed, away from foodstuffs. If fine dust is formed, dust/air mixtures can build up static electrical charges which may be explosive Page 3 of 7

Where insufficient ventilation, use suitable respiratory protection. Wear suitable protective gloves (e.g. Polyvinyl chloride PVC). After contamination with product change the gloves immediately. Chemical goggles/face protection. Wear suitable protective clothing. Avoid inhaling aerosols and vapours. Avoid contact with eyes and skin. Store work clothes and street clothes separately. Wash hand before breaks and at the end of work. Change contaminated protective clothing. Keep away from food, drinks and tobacco. 9.
